To all whom t may concern: y

Be it known that I, FRANK l/V. Buuren, a citizenof the United States,and a resident of San Diego, in the ycounty of San y Diego and State ofCalifornia, have invented certain new and useful improve ments inIlluminated Signs, of which the following is a specification.

My invention relates to illuminated signs in which each character shownupon the sign is composed of a plurality of convex surfaces upon which alight is thrown for illuminating` said convex surfaces and the objects.of my invention are, first, to provide a construction and mounting forsuch surfaces that will produce great efficiency of illumination;second, to provide a sign yof this class which is simple and economicalof construction and durable; third, to provide such a sign which may bemade in various shapes without decreasing the efficiency of theillumination and in which each illuminated dished plate may be lightedfrom all directions.

With these and other objects in view as will appear hereinafter, myinvention consists of certain novel features of construction,combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claim, reference beinghad to the accompanying drawings and to the characters of referencethereon, which form a part of the specification, in which:

Figure l is a side elevational view of a fragmentary portion of a sign,showing one of the characters thereon, Fig. 2 is a transverse sectionalview of a double faced sign, showing the characters mounted therein,Fig. 3 is a full sized detail fragmentary view of one of the sideplates, showing one of the dished plates which form the character on thesign, and Fig. Llis a side elevational view thereof.

Similar characters of reference refer to similar parts throughout theseveral views.

The side plates l, illuminated dished plates 2, top pieces 3, bottompiece 4, and lamps 5, constitute the principal parts of my sign.

The side plates l are preferably metallic sheets of the properthickness. Out of these metallic sheets are eut a plurality of holesforming the characters adapted to form one of the characters desired tobe shown on the sign. These holes are round except that Specification ofLetters Patent. i Patented Sept 7,1915, Application filed June 11, 1914.Serial No; 844,473.

there is left a plurality of supports la, preferably three, which are anintegral portion of the said metal. These supports l@ are Abent inwardlyVvand each" provided with 'a hooklb on its inner ends, adapted tosupport the illuminated dished plates 2 and hold saiddished plates inposition when the points lb are pressed tightly against said dishedplates. These illuminated dished plates 2 are preferably corrugated, asshown best in Figs. 3 and 4, which provides a better illuminatingsurface and are of a convex surface on their illuminating side, saidconvex surface facing toward the hole in the side plate 1.. This convexor illuminating surface may be painted in various colors and when thelight from the inside illuminates this convex surface, this dished plate2 will represent a light resembling a colored incandescent electriclight globe of whatever color the convex surface of this dished plate 2is painted. A plurality of lights are used in this sign, preferablyfour, so that the light from all four lamps from different directionsshining on the convex surfaces of said dished plates, intensifies theillumination thereon. The sign may be made double, as shown best in Fig.2, and the lamps will illuminate the dished plates forming thecharacters on both sides of said sign. The top 3, bottom t and endpieces carry the lights and the side plates which should be spaced aparta suficient distance, so that the lights will provide the properillumination to the convex surface of these dished plates 2. It isobvious that with this construction there is provided an illuminatedsign, which is simple and economical of construction, that the lampsthrowing rays of light from four or more directions onto each of thesedished plates will concentrate the rays on this convex sur faceproviding a very ehicient illumination of this dished plate. If thisilluminated surface is painted red, blue or other colors the sign whenilluminated will present an appearance very similar to incandescentglobes of the same color as these sections are painted.

Having thus described my invention what I claim as new `and desire tosecure by Letters Patent is:

In an illuminated sign the combination of metallic side plates spacedapart from each f other, each metallic side plate provided with aplurality of circular holes therein in suchr lil@ lil-5 a position as toform a plurality of characters, a plurality of leg members integral Withthe metallic side plates extending inwardly from the edge of each ofsaid holes 5 some distance, provided With bent portions on theirinwardly extending ends and a corrugated convex surface plate mounted in'said leg members sothat the convex Surface faces the hole from theinner side of said l0 platev and set back so that all of said convexsurface plate is set in from said metallic sido plate and means forilluminating said convex surface plates.

In testimony Whereof, I have hereunto subscribed my name in the presenceof tWo 15 subscribing Witnesses. l
